Patent DE-4122381-A1 (DE)
Inventor: ROSSMANN MANFRED DR ING
IPC: F27B1/16
Filed: 1991-07-05
Abstract: The invention relates to a process for running a cupola furnace for the production of cast iron. When running a cupola furnace, formation of CO, accompanied by advantages, occurs in the cupola furnace, above all in the fusion zone. This formation of CO varies with the coke filling level and, in certain operating cases, reaches undesirably low values. In order to counteract this, it is proposed that a coal gas (CO2 or CO) is introduced at a suitable rate into the cupola furnace at a suitable point, preferably in the region of the air inlet zone or fusion zone. <IMAGE>

Title: Suspension purificn. and pre-thickening - has inflow set according to outflow for max efficiency at a following discontinuous filter press
Inventor: STAHL WERNER PROF DR
IPC: B01D21/00
Filed: 1991-11-22
Abstract: The operation of an assembly to purify and prethicken a suspension, for a following filter press, has an adjusted inflow according to the outflow vol.. The inflow rate is pref. set above the outflow rate, by a given value, or it matches the outflow rate. The level of the inflow excess is set according to the torque or power input at the agitator of the appts., in relation to the outflow, or it is adjusted according to the concn. of solids at the overflow, or the solids content at the lower part or under flow of the appts.. The inflow can also be adjusted according to the vertical measurement of solids concn. in the appts.. A coupling to adjust the inflow according to the outflow rate is pref. placed between the inflow feed and outflow feed. The inflow feed has an electrical control, with a meter for the vol. or rotary counter for the outfow, to set the rotary speed of the inflow feed through measurement signals as the control parameters. The two feeds can be coupled mechanically with a common main drive. A redn. gearing is between the main drive and the feed for the inflow with a differential gearing at the first shaft input and an auxiliary motor at the second shaft input to give a different speed between the feeds. An additional inflow feed adjusts an overflow. ADVANTAGE - The assembly operates in a structured throughput for the max. efficiency of a following assembly which has a discontinuous action.
Patent DE-4138835-A1 (DE)
Inventor: GEIPL HERBERT
IPC: B23K9/173
Filed: 1991-11-26
Abstract: The invention relates to a protective-gas arc welding method using a melting electrode for relatively highly and highly alloyed, corrosion resistant steels, especially nickel materials and special steels, in which the welding process is carried out under protective gas. Welding methods of this type are associated, owing to the normally present oxygen contents or the contents of oxygen-carrying compounds in the protective gases, with undesirable oxidation at the welding point. Said oxidising proportions, on the other hand, do contribute to effective welding. According to the invention, a welding process is now proposed in which a protective gas having a proportion of carbon dioxide or a proportion of oxygen or a proportion of a mixture of said gases of from 0.01 to 0.5% by volume, preferably from 0.02 to 0.1% by volume is used. This results in an advantageous welding outcome while welding proceeds surprisingly well.

Title: Microstructuring substrate surface - by casting shadow of beam of atom agglomerates onto surface
Inventor: GSPANN JUERGEN DR
IPC: G03F7/20
Filed: 1992-08-19
Abstract: Microstructuring a substrate surface comprises using a mask, which is applied on to the substrate or laid on it, or kept at a certain distance from it, and formed by casting shadows onto the substrate surface. The novelty is that the shadows are cast onto the substrate surface using a beam of atom agglomerates. The beam is partially ionised before casted as shadow, electrically accelerated and/or electromagnetically adjusted. The agglomerates and/or agglomerate ions partially erode the material of the substrate surface at unmasked sites corresponding to the duration of the impingement with the beam. A material for the mask is chosen so that it suffers essentially low erosion by the beam of agglomerates or accelerated agglomerate ions. USE/ADVANTAGE - For prodn. of microtechnical parts. Reaction rate of chemical etching is increased.

Once the containers are positioned beneath the heads 31 the conveyor is turned off and the cap strip feeder is linearly moved into position beneath the heads, picking up caps on its receivers 24 as it moves. Magnets (32, Figure 2) may be used to attract the caps from the receivers 24 into recesses 34 when the heads are lowered. The cap strip feeder is withdrawn to its starting position below the chute before the caps are applied to the containers. The caps may be screw on, press on or crown closures, clamping holders 50 being provided to hold the containers against the worm conveyor during cap application. A fumigation frame 37 enables fumigation of the top area of the container with water vapour or gas.   <IMAGE>
